On my Windows 10 system I work with Nconvert version 7.136 to convert images to *.jpg images.
Using only Ascii characters inside the filename I have seen the following problem with *pgm images:
I use the following command
In case of SOURCEFILE is a *.pgm image (or maybe another filetype) the outputfile is created without file-extension ".jpg".
Code: Select all
nconvert.exe -half_res -ignore_errors -thumb 1920 1920 -overwrite -out jpeg -o OUTPUTFILENAME-without-extension SOURCEFILE
